Help! 2017 Tacoma tail lights don't work !

[oldmantaco]

Installed aftermarket LED tail light assemblies, but the tail lights don't work, the reverse and turn signals/flashers work, but plate lights don't, they all run off the same fuse, but the fuse is good, even replaced the fuse with a new one, still isn't working. I have LED license plate lights, but they worked fine until I installed the new tail light assemblies.
the tail lights work fine with direct power from the battery, but plugged into the harness, they don't work, I checked the power at the plug and nothing! I know it is in the tail light circuit since the plate lights don't work,, but the fuse checks good?? any help would be greatly appreciated! )

With the "hyperflash" turn signals, I had that symptom with aftermarket LED turn signals (all four) on my 2011 Corolla, and the fix was installing a different flasher module. Never had any trouble after replacing the module, or with any other LED lights. I changed all exterior lights to LEDs without trouble. You just gotta be careful, and know what you're doing. I was having trouble with a case study and decided to try https://www.topessaywriting.org/case-study-writing-service The writer provided a detailed, well-structured case study that met all my requirements. The service was fast and efficient, and the support team was very helpful throughout the process. It was a great experience, and it helped me achieve a high grade. I would definitely use this service again.

Wow, thanks for the video. I didn't know about it before.
